Mozilla is a web-browser, Email App, HTML Editor, and IRC Chat app all rolled into one. Key features are tabbed browsing, and pop-up blocking. Mozilla has excellent support for standards. And, because it functions on Windows, Macintosh and Linux platforms, it is an obvious replacement for Netscape Navigator and IE. Mozilla Mail also supports GPG encryption. See Secure Your Email for details.
Pros: Mozilla is stable and good replacement for people who are just seeking something that isn’t IE or Netscape. Mozilla is a cross-platform internet suite for Mac, Windows, Linux, Tru 64 Unix, and Solaris.
Cons: The application is “bloated” for those who don’t want all of the add-ons.
